“…The widespread sectioning version is the installa tion in a diode of return current conductors (RCCs) in the form of plates, which magnetically screen parts of the diode one from another [2]. The drawback of the sectioning is the need to ensure significant inter electrode gaps between cathodes and grounded hous ings of the accelerators or RCC plates, organizing the power supply to the cathodes of magnetically screened diodes, leading to significant changes in the design, and an increase in the diode size.…”

Results of the physical simulation and numerical calculations of magnetic field of the high power vacuum diode with a large electron beam cross section in the absence and with diode installed return current conductors in the form of rods are given. It is shown that the use of rods decreases the magnetic induction at the edge of the beam, while the field in the central part of the diode increases. It is found that the distribution of the magnetic field in the interelectrode cathode-anode gap in the presence of rods depends on the gap length between the back side of the cathode and the walls of the vacuum chamber. The location of the rods that halves the induction of the magnetic field at the edge of the cathode with the reasonable induction increase in the central part is found.

This paper reports on the properties of a supershort avalanche electron beam generated in the air or other gases under atmospheric pressure and gives the analysis of a generation mechanism of supershort avalanche electron beam, as well as methods of such electron beams registration. It is reported that in the air under the pressure of 1 atm, a supershort (<100 ps) avalanche electron beam is formed in the solid angle more than 2π steradian. The electron beam has been obtained behind a 45 µm thick Al-Be foil in SF6 and Xe under the pressure of 2 atm, and in He, under the pressure of about 15 atm. It is shown that in SF6 under the high pressure (>1 atm) duration (full width at half maximum) of supershort avalanche electron beam pulse is about 150 ps.

A high-current electron-beam accelerator for pumping of a Xe 2 lamp was developed. It is intended for injection of an electron beam into cylindrical gas cavity (diameter of 400 mm, length of 1600 mm, and the absolute pressure up to 3 bars). Two electron diodes in parallel are used in the accelerator. Each diode is connected to a linear transformer driver with vacuum insulation of a secondary turn. The next parameters of the accelerator have been obtained: diode voltage -550-600 kV, diode current -276-230 kA, current rise time -160 ns, maximum power of the electron beam -130 GW, pulse width on half maximum -160 ns, electron beam energy at power level not less than half of maximum value -20 kJ. The total energy of electrons, which pass through a 40 μm Ti foil into the Xe cell, is 8-9 kJ in the 150-160 ns pulse (full width at half maximum) mean specific power of energy input into gas cavity is about 330 kW/cm 3 . Design of the accelerator and test results are presented and discussed in this paper.
